Some specific applications have specific API's for handling transactions between Atlas and another system. These use a REST API and PHP notations for array (i.e. an array named "foo" with one item of the value "bar" is sent as "foo=bar" via the API) for communication. Unless otherwise specified, protected transactions are done with a timestamped HASH KEY
of your user credentials, to speed up operations and avoid sending API credentials with each request. To request your hash key, you use the REST function api_login()
with your API user and API key as arguments (in that order). This will return your hash key, which you can use for all requests that require authorization for 20 minutes from requesting it. After that time period, you need to acquire a new hash key.
